“…Additional important characteristics are its resistance to chemicals [ 26 ], heat resistance [ 27 ], adhesion to a variety of substrates [ 28 ], high tensile nature [ 29 ], and high electrical insulation and retention properties [ 30 ], including corrosion resistance [ 31 ] and high atomic number for greatly increased photon attenuation [ 32 ]. Epoxy resin is a synthetic polymer used as a composite radiation-shielding material [ 33 ] with other high-atomic-number materials, such as tungsten oxide (WO 3 ) [ 34 ], gadolinium oxide (Gd 2 O 3 ) [ 35 ], barium sulphate (BaSO 4 ) [ 12 ], bismuth oxide (Bi 2 O 3 ) [ 14 ], etc. Our results were in accordance with the radiation-shielding properties of epoxy resins with high-atomic-number composites [ 36 , 37 ].…”

“…Previous studies have found that new lead-free shielding materials have radiation-shielding properties by using components with high-atomic-number substances such as tungsten trioxide (WO 3 ) [ 11 ], barium sulphate (BaSO 4 ) [ 12 ], bismuth oxide (Bi 2 O 3 ) [ 13 , 14 ], and molybdenum trioxide (MoO 3 ) [ 15 ]. For example, the shielding properties from epoxy resin with nano-WO 3 for reduction of gamma rays from Cs-137 and Co-60 showed that the dose reduction was 46% and 34% for Cs-137 and Co-60 at 40% concentration in all samples [ 16 ].…”

Radiation protection in radiology is important because radiation may cause harm to the human body. The equipment for radiation protection is essential to ensure safe operations. Currently, there is widespread research on lead-free radiation shielding material. The aim of this research was to study lead-free material containing epoxy and iodine contrast media that was easy to form, low in cost, and environmentally friendly. The results showed that 2-cm material thickness with a concentration of 20% iodine had the greatest properties of radiation attenuate in the peak potential applied at technique 60–120 kVp, but the structure and strength of the shielding materials were decreased in accordance with increasing concentrations of iodine contrast media. It can be concluded that the lead-free epoxy radiation-shielding materials are able to absorb radiation at energy levels of 60–120 kVp. However, with improvement on homogeneity in the future, it could be used as a refractory shielding material in the radiology department.

“…According to the International Commission on Radiological Protection (ICRP), the effective dose limit for the whole body is 100 mSv over five consecutive years and 50 mSv in any 1 year for occupational workers [15]. Therefore, a radiological technologist (RT) and assistant who control portable X-ray machines must wear, or stay behind, high attenuation material shielding (i.e., lead, bismuth, or barium sulfate) temporarily during image acquisition to achieve a dosage that is as low as reasonably achievable (ALARA), thus minimizing radiation exposure [14,[16][17][18]. During COVID-19 epidemics, an RT entering infected zones is required to wear personal protective equipment (PPE) while a second worker waits outside the zone to remove cassettes without touching the wrapped outer layers, to minimize contamination [10].…”

The COVID-19 pandemic has resulted in a large increase in the number of patients admitted to hospitals. Radiological technologists (RTs) are often required to perform portable chest X-ray radiography on these patients. Normally, when performing a portable X-ray, radiation protection equipment is critical as it reduces the scatter radiation dose to hospital workers. However, during the pandemic, the use of a lead shield caused a heavy weight burden on workers who were responsible for a large number of patients. This study aimed to investigate scatter radiation doses received at various distances, directions, and positions. Radiation measurements were performed using the PBU-60 whole body phantom to determine scatter radiation doses at 100-200 cm and eight different angles around the phantom. The tests were conducted with and without lead shielding. Additionally, the doses were compared using the paired t test (p < 0.005) to determine suitable positions for workers who did not wear lead protection that adhered to radiation safety requirements. Scatter radiation doses of all 40 tests showed a highest and lowest value of 1285.5 nGy at 100 cm in the anteroposterior (AP) semi upright position and 134.7 nGy at 200 cm in the prone position, respectively. Correlation analysis between the dosimeter measurement and calculated inverse square law showed good correlation, with an R 2 value of 0.99. Without lead shielding, RTs must stay at a distance greater than 200 cm from patients for both vertical and horizontal beams to minimize scatter exposure. This would allow for an alternative way of performing portable chest radiography for COVID-19 patients without requiring lead shielding.
